How many 400 × 300 × 200 mm boxes fit in a 20ft container?

400 × 300 × 200 mm boxes of 400 × 300 × 200 mm (also called 40 × 30 × 20 cm cartons) in a 20-foot standard container (20GP) — inner dimensions 5,898 × 2,352 × 2,393 mm. Calculated by the Cubestow engine on 2026-09-08.

The answer in detail

A shallow quarter-Euro carton, common for apparel, books and small electronics.

The most common dry container for smaller export loads. Inner dimensions are typical for a steel ISO 20GP; individual boxes vary by a few centimetres, and the door opening (about 2,340 × 2,280 mm) is slightly smaller than the inside.

The simple grid estimate is 14 along the length × 7 across × 11 high = 1,078. The engine found 1,267 — 189 more than either uniform grid — by mixing orientations so that the leftover strip along the wall is used and by choosing the orientation that gives the most layers. The top view above shows the pattern.

Frequently asked

How many 400 × 300 × 200 mm boxes fit in a 20ft container?

1,267 400 × 300 × 200 mm boxes of 400 × 300 × 200 mm fit in a 20ft container (inner dimensions 5,898 × 2,352 × 2,393 mm), boxes may be laid on any side. That uses 92% of the 33.2 m³ available and weighs about 5,068 kg.

What are the inner dimensions of a 20ft container?

Typical inner dimensions are 5,898 mm long, 2,352 mm wide and 2,393 mm high (232.2 × 92.6 × 94.2 in), giving 33.2 m³ of space and a rated payload of about 28,200 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.

How much does a full load of 400 × 300 × 200 mm boxes weigh?

1,267 × 4 kg ≈ 5,068 kg, which is 18% of the 28,200 kg payload — so this load is limited by space, not weight.

How was this number calculated?

By running the Cubestow 3D load-planning engine on the exact dimensions above, allowing all six orientations, stacking with at least 80% base support and the container's payload limit, then re-validating the plan for overlaps, support and weight. Real loads leave room for dunnage, door clearance and uneven cartons, so treat the figure as the practical maximum.

Other cargo in a 20ft container

Assumptions. Cargo is modelled as rigid rectangular boxes with the outer dimensions above; the container's typical inner dimensions and rated payload are used; every box needs at least 80% of its base supported; no dunnage, straps or door clearance are reserved. The plan is one of many optimal or near-optimal arrangements — the engine's plan was checked for overlaps, support, orientation and weight, and the count is what it achieved within 1.4 s of search. Real containers vary by manufacturer; measure yours for tight loads.
